undo git commit after push code example

Example 1: undo commit git before push

git reset HEAD~

Example 2: git remove commits from branch after push

git reset --hard <last_working_commit_id>
So we must not reset to the commit_id that we don't want.

Then sure, we must push to remote branch:

git push --force

git commit -am "blabla"
git push -f <remote-name> <branch-name>

Example 5: undo last commit pushed

git reset # commitId

To reset a brancj to some good commit:

In the server, move the cursor back to the last known good commit:

Locally, do the same:

git reset --hard <last_known_good_commit>
